Speaking at an event Wednesday, David Dodge said, “We’re going to have some very unpleasant circumstances,” the Edmonton Journalreported. “There are some people that are going to die in protesting construction of this pipeline. We have to understand that.”

“Nevertheless, we have to be willing to enforce the law once it’s there,” Dodge said. “It’s going to take some fortitude to stand up.”

In an interview with the Journal, he elaborated by saying, “We have seen it other places, that equivalent of religious zeal leading to flouting of the law in a way that could lead to death.”

Dodge’s comments prompted outrage from climate activists.

Author and 350-org co-founder Bill McKibben warned, “North American governments have shown the ‘fortitude’ necessary to kill indigenous people often enough that this is no idle threat,” while Canandian author Naomi Klein called the threat a “disgrace.” She added, “If the worst happens, we now know they went into this with their eyes wide open.”
